Description
Technical field
The present invention relates to Nonwovens In Technology, be specifically related to a kind of high-hygroscopicity acoustical cotton and preparation method thereof.
Background technology
Noise directly affects the raising of people's physical and mental health and quality of life, for a long time in noise circumstance, can cause that hearing loss even may bring out some diseases.Will be away from noise, what we can do is exactly sound-absorbing and sound insulation.Acoustical cotton, the high-frequency noises vibrational energy that produces in life can be converted to acoustical cotton inside fine count fiber kinetic energy and lead into heat energy and disappear, reach the function of absorbing sound and lowering noise.
Acoustical cotton can be superimposed with multi-layer nonwoven fabrics, or other material of arranging in pairs or groups, and makes sound-absorbing, acoustic material.Nonwoven fabric is that textile staple or long filament are carried out to orientation or random support row, forms fibre net structure, presents many tiny gaps, this gap can be regarded hole as, has adsorption function, therefore, acoustical cotton can be considered porous material, has good sound-absorbing, heat-insulation warm keeping performance.Acoustical cotton is widely used in the industries such as building, electrical equipment, automobile, machinery as a kind of gasket material, mainly play the effect of sound insulation.But all there is more deficiency in existing acoustical cotton product and manufacture method thereof, main manifestations is: not environmental protection of manufacture craft; Sound-absorbing effect is general; Chemical resistance is low, cannot meet Code in Hazardous Special Locations instructions for use; Temperature resistant grade is low; Do not carry out flame treatment; Product caking ability is inadequate, fugitive, tension intensity is poor; Outward appearance and flatness are inadequate, thickness relatively large deviation etc.
Summary of the invention
Object of the present invention is just to provide a kind of high-hygroscopicity acoustical cotton and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of high-hygroscopicity acoustical cotton, by top coat, back layer, and the cellucotton layer being clipped between top coat and back layer forms, described top coat, back layer adopt nonwoven cloth material, and the nonwoven fabric described in it is characterized in that is made by meltblown by the raw material of following weight portion: isotactic polypropylene 100, polyethylene glycol 2-3, magnesium acetate 1-2, tetraethylammonium bromide 1-2, Firebrake ZB 3-4, paraffin oil 8-10, dioctyl ester 7-9, reed rod 12-14, purslane 2-3, frosted mulberry leaf 3-4, dandelion 2-3, moutan bark 1-2, auxiliary agent 4-5.
